Chapter 6: Eurasian Mongol Pax, Islamic Caliphates & Ottoman Hegemony

1. Genghis Khan & The Pax Mongolica

Under Genghis Khan (Temüjin) (1162–1227 CE), nomadic pastoral tribes united to forge the largest contiguous land empire in history:

  • Yassa: Genghis Khan's supreme legal-military imperial code.
  • Yam (Örtöö): An empire-wide network of relay postal stations operating at unprecedented courier speeds.
  • Pax Mongolica (13th–14th Century): Stabilized Eurasian trade routes, facilitating the journey of Marco Polo, paper money transmission, and printing/gunpowder dissemination between China and Western Europe.

2. The Ottoman Empire & Fall of Constantinople (1453 CE)

Sultan Mehmed II (The Conqueror) captured Constantinople on May 29, 1453, terminating the Byzantine Roman Empire:

  • Geopolitical Impact: Blockaded traditional overland Silk Road access for Western European merchants, directly catalyzing the Age of Discovery (Vasco da Gama 1498, Columbus 1492).
  • Devshirme & Janissaries: The institutional levy of young Christian subjects trained into elite imperial infantry (Janissaries) and grand viziers.
  • Suleiman the Magnificent (1520–1566): Reached the gates of Vienna (1529) and established comprehensive imperial law codes (Kanun).
